How to determine whether a specimen is a sporophyte or a gametophyte: Sporophyte is an asexual diploid phase, whereas gametophyte is a haploid generation that is sexual. Sporophyte(2n): the asexual, spore bearing generation of the plant, featuring diploid cells. By the process of meiosis, the sporophyte produces haploid spores. (meiosis) Gametophyte (n): the phase where gametes are formed.
